560 Classification of Animals. 
Cetaceae, Natatores, 
Glires, - - Grallatores, 
Ungulata, Rasores. 
A position, it will be observed, in regard to the Glires and Ungu- 
lata, different from that assigned to them by Mr M'Leay, but which 
we consider as more in consonance with the true analogies of the 
groups, and supported by a more extended analytical investigation 
of their contents. According to our author, the quadrumanous order 
is composed of the following families or primary divisions ; 1st, The 
Simiadce, or Apes and Monkeys of the Ancient World ; 2d, The Cebidce 
or those of the New World, constituting the typical and subtypical 
groups; 3d, The Lemuridce, or Lemurs; and 4th, the Vesperlilionidce 
or Bats, properly, we think, transferred to this order, (the station 
first assigned them by Linnaeus), -from that of the Ferae, in which 
they were placed by Cuvier. These form two of the aberrant divi- 
sions ; the third, which ought to represent the aquatic type, is want- 
ing, or has not yet been discovered. He then enters into an inte- 
resting detail and analysis of the first group, Simiadse, showing 
that the circle is perfect and complete, even following the arrange- 
ment of the family according to the analysis of MM. Cuvier and 
Geoffroy St Hilaire, from whence he deduces the important infe- 
rence, that Man, considered merely as a reasoning biped animal, 
cannot enter into the circle of this, the typical family of the Qua- 
drumana, much less into that of any other division of the order. 
The Cebidce, or monkeys of the New World, which constitute the 
subtypical group, are distinguished by their inferior size, and the uni- 
versal appendage of a tail, which member in the typical groups is 
long and prehensile. The wide space or septum between the nostrils 
is also a strong mark of discrimination, and they are besides desti- 
tute of cheek-pouches and callosities. The five typical forms of 
this family are represented by the genera Mycetes, Cebus, Calli- 
ihrix, Hapales, and Pithecia, and the passage from the Cebidce to 
the next family or Lemuridce, is effected by the intervention of the 
Aotus trivirgaiits, Humb. an animal possessing characters almost 
intermediate between them. The genus Lemur, distinguished by 
the long and ornamented tails, and the frugivorous habits of its 
members, he considers the typical group, assigning the subtypical 
station to the genus Otolictnus, 111. the members of which, in their 
general habits, are carnivorous. The aberrant groups are supposed 
to be represented by the genera Aotus, 111. Cheirogaleus, Geoff., and 
Galeopttkecus, Pall., which last, from its flying membranes, or the
